我是一个很长时间的stackOverflow潜伏者和第一次海报，所以如果我错过任何步骤或要求，我会道歉。我已经被困在这个bug上2周了，并且已经在网上广泛搜索了相关的bug，但没有解决我的问题，所以我希望你们中的一个人可以帮助解决这个问题！关于这一点的奇怪之处在于，它曾经工作过，我没有对代码进行任何更改，因此它是一个过时的API，我只是没有捕获或其他东西。
我有一个ListView，其中一个列表项包含一个带有地图的片段。加载ListView时，我遇到了这个崩溃：

知道发生了什么事吗？欢迎任何建议！谢谢。
答案 0 :(得分：0)
您将错误的上下文指向fragmentTransaction。尝试下面的一个。您可以使用view.getContext()获取视图的上下文。
更新
LocationFormCell构造函数，如下所示。
public LocationFormCell(Context ctx, CSFormElement elem, FormFragment frag, boolean editable) {
super(ctx, elem, frag, editable);
View view = LayoutInflater.from(ctx).inflate(R.layout.form_element_location, this);
Button overlayButton;
overlayButton = (Button) view.findViewById(R.id.overlayButton);
setupOnClickListener(overlayButton);
locationFrag = LocationMapFragment.newInstance(formElement.disp_name,false);
FragmentTransaction ft = ((FragmentActivity)view.getContext()).getSupportFragmentManager().beginTransaction();
ft.add(R.id.map_container, locationFrag);
ft.commitAllowingStateLoss();
locationFrag.setValue(value);
}
